Embodiment Construction

[0020] like figure 1 Place the measured beef on the rotatable stage 10 with a round hole in the center, and rotate slowly and steadily with the rotatable stage 10 under the drive of the stepping motor 11; the diffuse reflection optical fiber device 3 is eccentrically placed on the rotatable Below the stage 10, it consists of an incident optical fiber 2 connected to a near-infrared light source 1 and a receiving optical fiber 4 connected to a near-infrared detector 5, and the near-infrared detector 5 converts the collected near-infrared signal into an analog voltage signal, the analog voltage signal is converted into a digital signal through the analog-to-digital converter 6 in the microprocessor 7, and the digital signal is provided to the data processing module 8 in the microprocessor 7, and passed in the data processing module 8, and the data processing process like figure 2 As shown, firstly, the wavelet transform is performed on the spectral information, the noise is rem...

Abstract

This invention relates to a method and its device to determine the meat quality by use of multiple-spectrum analyze, which comprises near infrared source, near infrared detector, defused reflection light fiber apparatus, micro processor, display and record apparatus and rotation load bench. The method is the following: to project near infrared red light on the meat to get all spectrum information within the near infrared red range; to analyze the information to find out non-overlap wavelength windows and to extract the characteristics of each window to determine the quality of the meat though the analyze of multiple-variable model.

Description

Technical field [0001] The present invention relates to methods and devices for determining the quality of meat samples using multispectral analysis. In particular, it refers to a method and device for quickly detecting beef tenderness by using near-infrared technology. Background technique [0002] With the improvement of people's living standards, the production of high-quality beef is just in the ascendant in our country, and the quality evaluation of beef has been paid more and more attention by people. The most important indicator for evaluating the quality of beef is the tenderness of the meat. The tenderness is also the first consideration when establishing the beef grade evaluation standard. To a certain extent, the tenderness of the beef determines the price of the beef. Therefore, it is extremely important to detect the tenderness of beef. However, at present, there are two kinds of evaluations of beef tenderness, subjective evaluation and objective evaluation. T...
